Can I use Ferulic Acid with Phloretin?
Works well together
Ferulic Acid and Phloretin are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
Ferulic AcidAntioxidant
- ✓Antioxidant
- ✓Stabilizes vitamin C
- ✓Boosts UV protection
PhloretinAntioxidant
- ✓Neutralizes free radicals via HAT and SET mechanisms — potent antioxidant protection
- ✓Inhibits tyrosinase and reduces melanin precursors for brighter, more even skin tone
- ✓Clinically shown to reduce UV-induced damage markers in combination with vitamin C and ferulic acid
- ⚠Rare allergic contact sensitization reported (positive patch test at 2% in an atopic dermatitis patient, Contact Dermatitis 2024)
- ⚠Formulation-sensitive: requires pH 4–6.5 and a glycol/alcohol vehicle for stability; degrades rapidly outside this window
